Abstract: An apparatus for dispersing particles in a fluid, comprising: a flow divider for receiving the fluid and for separating the fluid into a first fluid stream and a second fluid stream; first and second fluid branches for receiving the fluid streams; a branch joining section for receiving the fluid streams, the branch joining section having a collision zone for allowing the first and second fluid streams to collide; a first nozzle that is arranged in the first fluid branch; and a second nozzle is arranged in the second fluid branch, the first nozzle comprising an orifice that is followed by a fluid diverging section.
Abstract: An emitter is arranged inside a tube and has: an emitter main body that is constituted by a resin molded body that has at least a recessed part and a through hole; and a flexible film that is joined to at least one surface of the emitter main body and that forms a flow path by closing off the recessed part and an opening part of at least one part the through hole. The emitter has a discharge amount adjusting part that is for making adjustments in accordance with the water pressure inside the tube. When the pressure of an irrigation liquid that is inside the tube is at or above a set value, the film slackens, and the discharge amount adjusting part narrows the flow path of the liquid and reduces flow rate.
Abstract: An aromatherapy device includes a housing forming two annular wells for retaining a scented fluid therein. Each well includes an insert positioned in the well to assist the retention of the fluid in the well by providing a second contact surface for the fluid to contact. The shape of the annular well and the viscosity of the fluid discourage the fluid from leaking out of the housing if laid on its side.
